Oolie,
I like your Smith's Red, does it taste good? I have some grafts growing so it should fruit next year.
Your Glen kinda looks like a small Washington Navel orange size. Nop, I don't know of what variety it is.
You should graft a Hamlin orange, I have one grafted and it gave me a fruit this year, it's very sweet, tasted better or as good as my Washington orange. The Hamlin seems to have a thicker rind, but it is seedless and very sweet.
Does your Glen orange have any seeds? Does it takes better than any of the Valencia orange and Smith's Red?
My Washington Orange taste is excellent, very sweet, can't eat a Valencia after you taste the Washington orange.
Smith's is good, I hate to say it has berry flavor, but it is different tasting than the regular Valencia, and if I had to compare the difference, it's closer to a blackberry. It's a heavily pigmented orange that seems to have indefinite hang time, so I do enjoy juicing them with regular Valencias in the spring.
The suspected Glen navel does have seeds infrequently like the Washington. When it does contain them there can be 5 or so, but often there are no seeds.
As far as taste, Smiths is reaching peak sugar levels now, and it maintains that for several months. The suspected Glen hit the right sugar-acid balance in November, but it now has lost most of the acidity and will continue gaining sugars through April/May. By then the internal membrane will be mostly shredded.
The regular Valencias hold multiple crops, the one in the photo is still building sugars, should be best in March or so, but right now they are on the sour side.
Thank you CB81. How about the smell of the peels? Any noticeable difference between the two?
